try flashing the gapps again, after you start google play it will ask you to add a google-account, it should work now. I had this once when i came back from ICS and it helped me.
[LG Optimus 2x] powwow88:
I tried those commands; last 2 says that File system still has errors but i formatted /cache and /data in cwm then how is that possible?
[LG Optimus 2x] snel76:
For all the poeple who have problems with su binary, i read somewere that using superSU intead of superuser has solved this problem and also the r/w issue. Maybe this could help, but i dont realy know, i used the method explained by morckx, wich worked well for me.
[LG Optimus 2x] Najmuddin NP:
What's the difference between DS battery driver and without DS battery drivers version ? Does it offer good battery life ?
[LG Optimus 2x] snel76:
yes DS offers good battery life but shows "funky" readings.So the percentage reading goes up and down related to actual battery cunsumtion.
[LG Optimus 2x] wawyed:
I just tried to install the new kernel and it broke my phone, It gets stuck trying to install it and now I can't flash a new rom. Don't know what to do.

Edit:

Ok, I formatted system/cache/dalvik cache and i could reinstall ROM without losing data.

[LG Optimus 2x] new2city:
I don't know about you guys but upgrading etana kernels 3.0.ys are getting very complicated, every new update require basically a complete sequence of

1. Reflash of new kernel or new kang which either hangs during which a battery pull is required

2. After reboot into recovery, then a reflash of the rom, followed by gapps (or else we lose our google account)

3. And then finally flashing of etana.

I don't mind doing this because vadonka's kernels are well worth it but just wondering when will this cycle end..
[LG Optimus 2x] @dap:
Hey, man, welcome to the cutting edge. ;)

Vadonka is working incredibly hard developing this kernel and you can't expect it to be perfect right out of the box. If the early wobbles get you down then wait a bit until some of the early kinks to get worked out before you flash.

And don't forget how lucky we are that we have somebody developing this kernel for our device. :)
[LG Optimus 2x] powwow88:
I restored my nand backup which has 120418 kernel and works well. Booted into cwm and executed these commands in adb shell:

e2fsck -fnC0 /dev/block/mmcblk0p1
e2fsck -fnC0 /dev/block/mmcblk0p2
e2fsck -fnC0 /dev/block/mmcblk0p8

Last 2 gave me error so i used "-fpC0" then checked again with "-fnC0" and there were no errors this time. I flashed latest Etana and checked again and only 2nd command gave error so i repaired it again with "fpC0". Rebooted phone but stuck again at 2nd LG logo. It seems no matter what I'm doing I just can't get latest kernel get it work on my phone.:confused: Just for curiosity after stuck 2nd lg logo I booted into cwm and executed these commands and last 2 gave me error again.:eek: I give up... kernel 120423 and me 3-0:rolleyes:
[LG Optimus 2x] morckx:
A temporary solution could be that temasek and MisjudgedTwat patch the updater-scripts of their kangs like this: http://xdaforums.com/showpost.php?p=24903664&postcount=3058. This should be no problem for other kernels, I guess. @temasek, @MisjudgedTwat ?

An even more satisfying solution would of course be an explanation to the problem ;)

Has anyone already tried to replace or patch the update-binary? Its format routine at least seems to contribute to the problem.
[LG Optimus 2x] devazg:
still stuck at 2nd LG logo, but now I get FCs on Google play store with the 18th apr version (everything worked before)
[LG Optimus 2x] joe1660:
i installed the last version and stuck at second lg. i try to install back the 18/4 and i have mount problem so the "packing kernel failed"

i am in adb shell and type mount so i have this:
[LG Optimus 2x] joe1660:
you can read now the attachment
[LG Optimus 2x] joe1660:
now i cant install any of your kernels. only the imperictus
[LG Optimus 2x] Sörnäinen:
To me that sounds as if the problem is in CWM. I would reinstall that, it seems to be damaged.

Just my 2ct, maybe I am totally wrong.
[LG Optimus 2x] joe1660:
its not cwm problem, the problem is to the system folder because the kernel installation cant take access
[LG Optimus 2x] redh4t:
improvement and system/ r/w

I am using ETaNa HOC LITE OTF 2.6.32.59 version at the moment. If i update to newest 3.0.29 ETaNa kernel, i would notice any different in performance, battery life etc.?

Oh and i tried 3.* kernel some while ago, and they had this bug with r/w system/. Could not get r/w rights to system/ dir. This will happen again if i am going to flash this kernel? Or everything should be fine?

Thanks.
[LG Optimus 2x] vadonka:
the "stable" version is 2.6.32 so if you dont like the beta test use that version.

no need any reflash or else. if you have issues you probably have fs corruption or something else.

if you do everything is right after the kernel flash everthing will be working. no need to reflash the gapps or else.

many issues not related to the kernel so guys please spare my time :)
[LG Optimus 2x] elvnox:
Hello, thank you for your work but your newest kernel hangs at boot (Miui)
[LG Optimus 2x] redh4t:
What do you mean by that? I just wipe dalvik if needed and flash the kernel. Then reboot. Is there anything more to do? And how about performance, battery life etc. i wrote? I did not try your latest kernel that is why i am asking.
[LG Optimus 2x] upetro:
I just dont get it. How can it be that i just cant get the latest kernel to work. I even tried running the Format the system partition with the script here:http://xdaforums.com/showpost.php?p=24709087&postcount=2894 and the Re-init the system partition with the script here: http://xdaforums.com/showpost.php?p=24920215&postcount=3089.

But nothing works, it just hangs at the second LG screen.

Did anyone with the same problem(hanging at the second LG screen) get it working?
[LG Optimus 2x] Cydras:
Have you recovered the backup?
[LG Optimus 2x] sind500:
The last 3.0.y used with miui doesn't work. It stops at boot
[LG Optimus 2x] Sörnäinen:
same here. Installed .18 back.
[LG Optimus 2x] zait83:
Tried latest version and with my Connected to usb it boots up. Remove the cable and it freezes. If I try to boot without cable it freezes on second LG screen.
[LG Optimus 2x] kennbo82:
Hi Vadonka,

does your v.2 also have a hardcoded max. cpu-freq for screen off or do I have to use apps like SetCPU for it?

I tried v.3 but so many problems and always I have to reset everything because CWM cannot mount /system in order to restore a backup or something else. It takes too much time to fix this again and again. :(

kind regards

kennbo
[LG Optimus 2x] new2city:
Sorry vadonka, just sharing my experience with the beta kernel. your 3.0.y kernel's are just difficult to resist... Sometimes, I feel like a moth flying around a bug a flame.. :)

Have been with your kernel's since your day's in the iron kernel forum.
[LG Optimus 2x] antec123:
you're not the only one, i did format system and install cm7 rc1-91 and flash the kernel 2304 not beta and it stuck on LG 2nd boot. and even i downgrade to rc1-83 with kernel 2304 it can't pass LG 2nd boot :(

right now my configuration in rc1-83 and 1804 kernel, all is fine and work so smooth no r/w bugs and no shutdown it self after charging. i'll wait for the upgrade kernel for vadonka maybe already stable :cool:
[LG Optimus 2x] hadi_rena:
AFAIK our device lack 'something' which caused cpuspy is not possible.

Suppose:

data partition corrupted

make cmw backup

formating data partition

restore cmw backup

Will data fs corruption fixed and data restored or corruption still persist ?

UPDATE:

Sorry for noob question and I have checked it.

Will data fs corruption fixed and data restored or corruption still persist ? YES (tested)

I Have system, cache, data FS corruption now have been fixed. Still use kernel from 18 apr. Later will try latest one and give the result
[LG Optimus 2x] eyronic:
The latest kernel stucks on the 2nd logo of LG. No mounting errors on system, cleaned cache and dalvik but still stuck on the 2nd logo.

Flashed back the kernel from April 18 and it works.

Conclusion, the latest kernel is faulty one?
[LG Optimus 2x] vadonka:
try the today version
[LG Optimus 2x] Trystan34:
So should I try the Shared Memory Version first or the normal version?
[LG Optimus 2x] owain94:
doesn't matter if your phone is working fine now you can leave it like this otherwise flash one of the two
[LG Optimus 2x] Trystan34:
Ok thanks.
[LG Optimus 2x] vadonka:
the last version of my kernel running in my phone (powersave undervolted), my second test phone (standard), my three friends phone (powersave). all running great no bsod, fast and smooth great battery life (its the best version for me personally). temasek cm7 kang 31-33

i still wait for the feedback from who have boot problem with the previous version.
[LG Optimus 2x] Rankec:
I had some reboots while using your last version (11. January) . Hope your new version fix this problem.

Btw: miui theme with standard powersave version is working
[LG Optimus 2x] antec123:
I use your latest kernel non uv 12jan share 32mb, get black screen when play smurf village. Have to pull off the batery. With Kang 32
[LG Optimus 2x] vadonka:
the shared memory version possible that causing such this issues... its not bug free thing like the korean developer say to me :confused:

try the traditional ramhack version or the basic version instead of the shared memory version.

i write this on the OP, if you have problem with the shared version try the other two :)
[LG Optimus 2x] hardmankam:
I too have some problems booting after flashing your Kernel. The 1st LG screen comes up and then the screen turns black and will not boot up. This is with your Jan 12 built.

I have also tried the removal script after flashing the Kernel, but still no go.

My phone info:

CM7 P204-34 Kang

RIL: 0725 (V10d) + BB 1035.21_20110725
[LG Optimus 2x] vadonka:
what version you installed?
[LG Optimus 2x] vadonka:
who still have boot problem try this: http://www.donka.hu/android/kernel/LGE-KaNG_kernel_only_120112.zip

this will install the default standard kernel only with the modules and nothing else.

its the best for a fresh cm7 install, or at least reflash the cm7 withgout data wipe for make sure that your system partition is free from any tweak.
[LG Optimus 2x] 4lph4:
All working well with the shared memory UV version. Thank you Vadonka :)

One question about swap : every time I use the free command in terminal, I see the swap almost empty (few KB used), is this normal?

Inviato dal mio Optimus 2X usando Tapatalk
[LG Optimus 2x] grognaz:
i have boot problems with that version, i wiped cache and dalvik, reflashed themask's kang #34 and flashed that kernel and on first boot it hanged on the blueish lg log. 2nd time it booted, then i rebooted and it hang again at the bootanimation.

LGE-KaNG_PowerSaveShared_CoreBoost-120109 this is the last version that works for me without reboots or boot problems.

EDIT: how can i make sure i have no tweaks on my system? is a installation of cm7 with cache and dalvik wipe enough or are there leftovers somewhere?
[LG Optimus 2x] vadonka:
yes, its normal the swap is used not too often, thats why i lowered the swap size to 50mb, its more than enough.
[LG Optimus 2x] vadonka:
the difference between the 2012.01.09 and the latest release is that

-updating the bfq io scheduler to v3r1 (other kernels have this and no problem)

-the second is the zcache/cleancache backport from the kernel 3.x

thats maybe causing some interference, but why just some people?

i build this latest version without the zcach/cleancache, only just the standard no undervolted and you guys who have problem with the latest version try this what i posted soon.
[LG Optimus 2x] vadonka:
here is test version what i mentioned

try this first:

Zcache disabled version

still not boot, try this:

Zcache and Zram disabled version

and finally...

Zcache Zram and memory compaction disabled

even the first version is technically is the same as the jan09 version

please give me a feedback about the results.
[LG Optimus 2x] grognaz:
thanks a lot, i tested the first and second kernel and i dont have any boot/reboot problems with either of them.

however, the first with zcache disabled has a problem, mkswap is all the time using about 50% cpu.

ive done more than 10 reboots with these 2 kernels and didnt have a single problem.

what i noticed when i checked the cm7 performance setrings the first time that no option was selected for compcache. any idea if this or any other performance setting could cause problems with zcache?
[LG Optimus 2x] vadonka:
its just a test version...

so the problem is the zcache, finally! :)

im disabling the zcache for now.
[LG Optimus 2x] grognaz:
i know, just wanted to mention it in case it could cause a problem:D

glad i could help, lets hope its the same for all the problem devices:O
[LG Optimus 2x] vadonka:
im patched the zram driver as well so its related to the zcache, but it seems not every device will handle. its better that remove for now and revert the zram driver.

good news im leaving enabled the memory compaction in the first two test version, so its working. better than nothing :)
[LG Optimus 2x] grognaz:
indeed:D

will the zram overwrite the compchache ram ? and if so what will changing che compcache amount in cm7 performance option do to that orbwhat should it be set to?
[LG Optimus 2x] alakyr:
if mine work with first 23th april version i can still use this till next update right?
[LG Optimus 2x] vadonka:
yes

today version is the same like yesterday, just i used a new fresh installed clean build server.
[LG Optimus 2x] plakers:
Installed that 24th version, it seems to do the same - no boot at all, stuck @the second LG Logo as is was the case with the 23th one (even with e2fsck, gapps reinstall etc...)

EDIT : After 24th and 23th installation, always got a "Packing Kernel Failed" under CWM - even if resintalling the 18th one... > My 18th ROM was restored: "Error mounting /system" & so many errors related to FS... I'm stuck even under CWM :(

nb. I had many freezes when SDCard mounted via USB link to my computer, even with functionnal ones.
[LG Optimus 2x] eyronic:
It's still stuck at the 2nd logo. Flashed back the kernel from Apr. 18 and it works again.

I also got the same problem with plakers. The phone freezes when I mount my phone to the computer.
[LG Optimus 2x] tomislav177:
Today version stuck at boot animation.
[LG Optimus 2x] plakers:
The only way I found to get back, as I don't have ADB here :

1) Factory Reset

2) Reflash the whole CM7 Kang

3) Install GApps

4) Install the 18th Kernel

5) Reboot in recovery again : Restore my CWM Backup

I expect that the error messages 'Packing Kernel Failed' and the many FS erros on /system are related to binary/utilities corrupted by the 23/24th installation? I didn't have any problem of that kind before.

First boot (after full boot, and SIM unlock) gave me a freeze/reboot, but now it seems to work again with Temaske's-91PDroid and the 18th Version - and all my apps/data is back, Ouch!

:)

Last but not Least : I DO use the classic CWM version, not a Touch one...
[LG Optimus 2x] FlynDual:
I had the same situation! ....:S
[LG Optimus 2x] extreme79:
Have you installed the latest version (24Apr)?
[LG Optimus 2x] powwow88:
Same here.:( Btw. how is that it works for a few people but doesn't work for others? Did LG make two different kind of P990?:confused:

For me not boot animation it's 2nd LG logo.
[LG Optimus 2x] plakers:
Yep, 4 users report a boot problem (and some other errors)... It seems to be better safe to keep your current version for now (and/or the 18th one)

---------- Post added at 02:19 PM ---------- Previous post was at 02:14 PM ----------

@Vadonka :

- should it be possible to keep the last stable known version (the 18th) in the repository please?

- also, for the new ones, the problem seems to be related to FS "corruption" or binary/system files overwrite (an automatic fsck before/after flash could be usefull?)

- I'll try to perform a "redo" tonight, and give your the 18th /system info (fs and files) and the post-24th flash, to trace differences - if you need it!

;)
[LG Optimus 2x] TweetyPeety:
today version works good except WIFI doesn't work, can it be that you changed something there ???
[LG Optimus 2x] eyronic:
It works on you? What on the 4 kernels did you use? I tried OC DS and it doesn't work on me.
[LG Optimus 2x] plakers:
same here, the DS/OC one...
[LG Optimus 2x] _Vegas:
everything works fine here:rolleyes:
[LG Optimus 2x] powwow88:
I think he's using chuck norris rom maybe that's why but few people said yesterday that it's working on temasek kang and i'm usin temasek kang 92 and i have tried 120423, 120424 Non DS/OC but stuck at 2nd LG logo.

Anyway, WIFI only works when Chuck Norris wants it! :D
[LG Optimus 2x] plakers:
Oh please, Chuck, make that latest build work with all CM7/Kang Roms! And if you can, PLEASE, go to find NVidia lamers and BITE THEM ALL to get the sources that our lovely devs' need! :p
[LG Optimus 2x] powwow88:
+1 I tested today's STOCK and it's working so only problem with OC version just like with the 1st etana 3.0.y.

I should have tried that earlier. I guess STOCK 120423 would work too.

Just as I thought. I flashed 1204231623-ETaNa_STOCK_OTF-3.0.y and it's working.
[LG Optimus 2x] eyronic:
So the problem is on the OC version? I haven't tried the stock.
[LG Optimus 2x] AlexanderKgr:
24 april version oc non-ds boots as normal after 4 minutes...:):)
[LG Optimus 2x] csunny95:
Have flashed the latest kernel.

But the device always freeze( no response in touching the screen and pressing any key.). Also, it sometimes can't wake up in standby mode.

Is anyone having this issue??:confused:
[LG Optimus 2x] antec123:
+1 i'm using RC1-83 and stock latest kernel. i think the OC has problem...

but with stock, the temperature of proc can't be monitoring
[LG Optimus 2x] kickokim:
Ok, todays Stock version works for me, oc freezes on boot animation. It seems very smooth!
[LG Optimus 2x] extreme79:
I've installed the today revision after the classic spring cleanings (cache & dalvik) :P and after some minutes (normal afeter a cleaning, have patience!) it boot normally.

When @ home I'll check the WiFi Functionality .

Actually I've updated My Ril to 725 v10 (like BB) instead of ril 218 and it seems to works great.
[LG Optimus 2x] morckx:
My phone is working equally fine with 1204230922-ETaNa_OC_OTF-3.0 (compiled with gcc 4.7) and 1204241137-ETaNa_OC_OTF-3.0.y.zip (1.4GHz, default UV, no zram, 48MB ramhack) in combination with temasek's RC1-92. Also the slight battery drain I had with the 120418-version seems to be gone, but it's probably too early to say that.

Last time I had boot problems, I had an outdated su and/or corrupted fs.

Edit: Phone hangs now from time to time for a few seconds. Will check if this could be KSM related...
[LG Optimus 2x] eyronic:
Will you re-upload the 1204230922? :D
[LG Optimus 2x] dmxl:
sdcard recognition?

Hi there,

I installed the 1204021107-ETaNa_LOC_LITE_OTF version yesterday. And I noticed that sometimes after rebooting, my phone doesn't recognize the sdcard, until I reboot again. I suspect the two are related, because I didn't have this issue without the kernel.

Any idea why this could be happening? I'm using the kernel in combination with the latest nightly build of CM7.

Thanks
[LG Optimus 2x] plakers:
Did you perform any e2fsck task before reinstalling the latest version? It seems the OC has a problem with the 24th one... May be my problems are related to yours (previously)?
[LG Optimus 2x] kickokim:
I have better screen off battery, but screen isn't any better, it might actually be worse...
[LG Optimus 2x] elektrotof:
Hi,

I have tried several version of Etana and i had a problem with the one of 22 or 23/04. I flashed and then my phone freezed, and was unable to boot.

I decided to do a full wipe then i reinstalled Temasek Kang (92,77 etc etc) and I do have a problem on all of these kangs : it is impossible to create a google account. I can only add an exchange accout.

I ve installed the latest gapps ...

Does anyone have an idea to make CM7 works again?

I can only install other ROMs (like modaco, or gueste2x hybrid)

What's wrong with this f*** p990?

Thank you for your help
[LG Optimus 2x] eyronic:
Tried 2 kernels from today's version (April 24). The OC DS and the OC. The OC DS is stuck on the 2nd logo of LG but the OC works like a charm. Thanks vadonka. :D
[LG Optimus 2x] morckx:
Look at me previous posts. I'm the one who almost put this into his signature :D

Last time I had this problem is, fortunately, 10 days ago
[LG Optimus 2x] FlynDual:
Hi! I had the same problem;) you should just try to flash gapps again!
[LG Optimus 2x] buedi:
Still the boot hang problem with the latest version :-/!
[LG Optimus 2x] upetro:
Me too. But the 18.April version works like a charm. I dont get it.
[LG Optimus 2x] new2city:
to guys with problems with etana 3.0.y

it's frustrating not to flash a new etana... but it is very difficult these days.

As we have guys who have NO issues at all and guys like me who suffer lost google contacts(once is ok but every time!) and hang ups after flashing etana 3.0.y. Maybe we should start helping ourselves and pool our resources and find out what is different or similar with our phones. For me, I have done basically everything I can gather here

1) Factory reset and re install, ROM and etana. All is fine until I flash a new etana or new ROM, BTW, I use Temasek's unofficial all the time.

2) I check my file system(using windows scandisk) and all is fine.. any more reliable way?

3) Install supersu and it is still the same WHEN I flash a new etana over an old version.

So, could it be the baseband? i have not flashed a baseband in months.. Anyway I am using 725(1035.21.201110725), what are guys are you using( for those with no issues and those with issues)?
[LG Optimus 2x] powwow88:
My only issue that latest OC version stuck at 2nd LG logo. STOCK works like a charm. 120418 OC works. My BB 725, RIL 218 but this BB/RIL combo won't work for everyone cuz it depends which country you're in and which provider. I use Temasek's unofficial all the time too.
[LG Optimus 2x] extreme79:
For me the latest kernel works great, no issues!

I use bb725 + Ril 725 (v10d)

No boot hang issue.

No R/W issue before kernel install

I think the rw issue could be the source of the problem.. maybe if you install new kernel having the rw issue, something could not be written and the phone hangs at startup.. but I'm not sure.

How can you obtain these fantastic results??

You use mobile data always on? Gmail/fb/tw sync?

Can you provide us a battery stats to understand what we are doing wrong?

Today, for instance, after a night in airplane mode (-1%, very good), I used my phone a little (no radio, no mp3, no game, only a 5 min browsing or less, only two short calls) .. and at 20 o'clock the phone was dead.

What BB+RIL you actually use?
[LG Optimus 2x] powwow88:
I had that rw issue but re-init_system_as_ext4.zip fixed that and if I don't change rom I only have to flash kernels and no rw issue.
[LG Optimus 2x] dmxl:
Very good question.
[LG Optimus 2x] Keltek:
I have some question for those whom the new kernel works

- do you have OC or STOCK kernel?

- do you use something to overclock/undervoltage?

- did you make some special settings especially in etana.conf file?

Thank you.

Why I ask - my idea is that it is an undervoltage problem, coz it is related only to OC version and I have very very strange values of undervoltage in PimpMyCpu
[LG Optimus 2x] extreme79:
- I use the OC kernel

- Enabled Undervoltage from etana tool

- not overclocked, limited to standard clock from settings (no more setcpu,pimpmycpu etc).

- no special settings, only enabled update su line.
[LG Optimus 2x] elektrotof:
That's what i tried but unsuccessful. Guest2x based on Kang 64 works like a charm now. Flashed with etana of 2012/04/02. I'm now "affraid" to flash a new kernel version :' ) (especially 3.y one)
